Find a polynomial function of lowest degree with rational coefficients that has the given numbers as some of its zeros. 5i, square root of 5

Question

Please help me understand by explaining this problem to me and putting in a polynomial function could not use the symbol so I had to type out the square root of .. instead of the actual symbol.

Answer 1

P(x = (x - 5i)(x + 5i)(x - √5)(x + √5)
